Learn to use the Runway Gen-4.5 video model to generate videos from text prompts in Timeline using Adobe Firefly.
Timeline is a beta feature in Adobe Firefly, now available for testing and feedback.
You can transform your creative ideas into videos using partner models to generate models in the Timeline. With the Runway Gen-4.5 model, you can convert text descriptions into high-quality video clips that you can add directly to your timeline.
Select the Generate media icon in the right panel, then select the Video panel if needed.
Enter a descriptive text prompt in the prompt box explaining what you want to generate.
Select the Model dropdown menu under General settings, then select Runway Gen-4.5.
Select the desired Duration for the generated video from 5 seconds, 8 seconds, and 10 seconds.
Nota
You cannot change the Resolution and Aspect ratio of the video generated with Runway Gen-4.5, which are set at a default of 720p and Widescreen (16:9), respectively.
If you want to add a first frame for the video generation, under the Frame section, select First and upload the image.
In the Advanced settings, use the Seed option to add a seed number that helps start the process and controls the randomness of what the AI creates. If you use the same seed, prompt, and control settings, you can generate similar video clips.
Select Generate to generate the video.
Drag the generated video from the Generation history panel onto your video timeline.
Your generated video is now part of your project and can be edited, trimmed, or combined with other media clips in the timeline.
